Title: Graphite vapor-deposited contact pin and ic socket pin using this contact pin
Inventor: WATANABE MASAO
IPC: H01R13/03
Filed: 1994-09-06
Abstract: PURPOSE: To enhance the contact reliability and prolong the life. by vapor- depositing graphite on the surface of a contact pin. CONSTITUTION: Graphite vapor-deposition 11 is formed on the surface of a contact pin 20. The contact reliability and durability of the graphite vapor- deposited contact pin 20 or IC socket pin, which is repeatedly slid and attached/ detached, are enhanced. As means for forming vapor deposition of graphite, coating treatment by vacuum deposition with electron beams is one example. The socket pin having the graphite vapor deposition 11 has a function to prevent the formation of a gold-lead alloy on the surface of gold caused by sliding of the contact surface. As a result, the formation of tin oxide caused by remaining tin and oxygen in the air, which is a main cause to increase contact resistance, is suppressed. By the graphite vapor deposition 11, contact surface with less friction resistance can be obtained.

Title: Pulse width integrating and measuring instrument
Inventor: KITAMURA TORU
IPC: G01R29/02
Filed: 1986-12-15
Abstract: PURPOSE:To measure the integral pulse width of a discontinuous pulse train to be measured in a short time regardless of whether or not there is periodicity by integrating a reference clock which is outputted according to the pulse width of the discontinuous pulse train to be measured by a counter. CONSTITUTION:The discontinuous pulse train S to be measured is applied to one input terminal (a) of a gate 1 and a reference clock CK is applied to the other input terminal (b) from a reference clock generator 2. The period of this reference clock CK is much shorter than the pulse width of the discontinuous pulse train to be measured. Then, the counter 3 counts the pulses of the reference clock CK outputted according to the pulse width of the pulse train S. Consequently, the integral value of the pulse width of even a single-shot pulse train having no periodicity is measurable.
